Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal pump processing, in particular to an automatic paint spraying device for centrifugal pump processing. Background Art

[0002] There are many types of centrifugal pumps, such as vertical, horizontal, single-stage, multi-stage, single-suction, double-suction, and self-priming. Centrifugal pumps work by using the rotation of the impeller to cause the water to undergo centrifugal motion. Before starting the water pump, the pump casing and the suction pipe must be filled with water, and then the motor is started so that the pump shaft drives the impeller and water to rotate at high speed. The water undergoes centrifugal motion and is thrown to the outer edge of the impeller and flows into the water pressure pipeline of the water pump through the flow channel of the volute pump casing.

[0003] During the processing of the existing centrifugal pump casing, it is often necessary to spray paint the casing to increase the service life of the casing. When spraying, the traditional casing is often clamped on a turntable and sprayed with a manual handheld spray gun, but the quality of manual spraying cannot be effectively controlled. During the spraying process of the centrifugal pump, the paint used for spraying will be stored in a paint box or a paint cavity. The paint will be in a static state for a long time, which will cause the surface paint to solidify, resulting in poor spraying effect and being unfavorable for spraying. In addition, when spraying, the existing centrifugal pump rotates the centrifugal pump to spray paint in all directions of the centrifugal pump. Due to the large size of the centrifugal pump, the spraying of the centrifugal pump will be uneven. A solution to the above problems is proposed below. Utility Model Content

By installing the discharge pipe 24, when the paint needs to be replaced, it can be discharged through the discharge pipe 24, and clean water is discharged through the feed pipe 23 to clean the paint storage chamber 2.

[0023] A stirring assembly 3 for stirring the paint is provided in the paint storage chamber 2. After the paint for spraying is added into the paint storage chamber 2, the stirring assembly 3 can be started to stir the paint so that the paint can flow in the paint storage chamber 2 to prevent the paint from solidifying.

[0024] The stirring assembly 3 includes a stirring rod 11 and a driving motor 12. A wide groove 13 is opened on the spray box 1. The driving motor 12 is installed in the wide groove 13. The stirring rod 11 is rotatably set in the paint storage chamber 2. The driving motor 12 passes through the spray box 1 and is fixedly connected to the stirring rod 11. A sealed bearing is installed on the inner bottom wall of the paint storage chamber 2. The sealed bearing is divided into an inner ring and an outer ring. The output shaft of the driving motor 12 is fixed to the inner ring of the sealed bearing. When the paint needs to be stirred, the driving motor 12 can be started first, and the stirring rod 11 is driven to rotate in the paint storage chamber 2 by the output shaft of the driving motor 12, so that the stirring rod 11 can drive the paint to flow. The sealed bearing is connected to the output shaft of the driving motor 12 to prevent the paint from leaking.

[0025] The spray box 1 is provided with a spray chamber 25, in which a positioning plate 8 is rotatably and slidably provided, and the positioning plate 8 is provided with a plurality of positioning threaded holes 9 corresponding to the centrifugal pump. During the spraying process, the centrifugal pump can be installed on the positioning plate 8, and the flange on the centrifugal pump corresponds to the positioning threaded holes 9 on the positioning plate 8 to achieve fixed installation of the centrifugal pump. An adjusting component 10 for driving the positioning plate 8 to rotate and lift is also provided in the spray chamber 25.

[0026] The adjustment assembly 10 includes a connecting plate 14, a driving motor 15 and an electric push rod 16. A wide groove 17 is provided on the end surface of the spray box 1. The electric push rod 16 is installed in the wide groove 17. The push rod of the electric push rod 16 passes through the spray box 1 and is slidably arranged in the spray chamber 25. The connecting plate 14 is rotatably arranged on the top of the electric push rod 16. The connecting plate 14 and the electric push rod 16 are connected through a bearing. The driving motor 15 is installed on the top of the connecting plate 14. The positioning plate 8 is installed on the driving motor 15. The positioning plate 8 and the driving motor 15 are connected through a positioning screw. When performing the spraying process, the driving motor 15 can be started first, and the driving motor 15 is connected through the positioning screw. The positioning screw drives the positioning disk 8 to rotate, and the positioning disk 8 drives the centrifugal pump to rotate. A protection frame is also installed on the top of the connecting disk 14, and the driving motor 15 is installed in the protection frame. The protection frame protects the driving motor 15 to prevent the paint from being sprayed onto the driving motor 15 during subsequent painting. A gap is left between the top of the protection frame and the positioning disk 8 to prevent the protection frame from interfering with the rotation of the positioning disk 8. When the driving motor 15 is running, the electric push rod 16 will also start, and the electric push rod 16 will perform reciprocating lifting and lowering motion, thereby driving the positioning disk 8 and the centrifugal pump to perform reciprocating lifting and lowering for subsequent spraying processing.

The feeding pipe 7 will spray the paint through the paint spraying pipe 20, thereby realizing the painting process of the centrifugal pump.

[0029] Two sealed doors 21 are hinged on the end surface of the spray box, and the two sealed doors 21 correspond to the spray room 25. The sealed doors 21 are provided with observation windows. The sealed doors 21 are installed to prevent the paint from emitting to the outside of the spray box 1 during paint spraying and affecting the health of the operator. An inspection door 22 is also hingedly installed at the position of the spray box 1 corresponding to the equipment slot 4. The inspection door 22 serves to protect the paint pump 5.

[0030] Detailed analysis of working principle:

[0031] In the process of spraying the centrifugal pump, the paint for spraying is first added to the paint storage chamber 2 through the feed pipe 23 for storage. The design of the paint storage chamber 2 ensures that the paint can be fully stored to provide sufficient material for subsequent spraying. Next, the drive motor 12 is started. The drive motor 12 is connected to the stirring rod 11 through its output shaft, driving the stirring rod 11 to rotate in the paint storage chamber 2. The rotation of the stirring rod 11 causes the paint to continue to flow in the paint storage chamber 2, preventing the paint from solidifying due to long-term stillness, and ensuring that the paint maintains a uniform flow state.

[0032] The centrifugal pump is fixedly installed by the positioning plate 8. The positioning plate 8 is provided with a plurality of positioning threaded holes 9 corresponding to the flange of the centrifugal pump, so that the centrifugal pump can be firmly fixed on the positioning plate to ensure that the centrifugal pump will not move during the spraying process. A driving motor 2 15 is provided to realize the rotation of the centrifugal pump. The driving motor 2 15 is connected to the positioning screw 18 through its output shaft, and the positioning screw 18 is threadedly connected to the positioning plate 8, thereby driving the positioning plate 8 and the centrifugal pump to rotate together. At the same time, the reciprocating lifting and lowering of the centrifugal pump is realized by the electric push rod 16. The electric push rod 16 is installed in the wide groove 2 17, and its push rod part passes through the spray box 1 and is slidably arranged in the spray chamber 25. The top end of the push rod of the electric push rod 16 is connected to the connecting plate 14, and the connecting plate 14 is further connected to the positioning plate 8, so that the reciprocating motion of the electric push rod 16 can drive the positioning plate 8 and the centrifugal pump to be lifted and lowered.

[0033] After the centrifugal pump is fixed and the height is adjusted, start the paint pump 5. The paint pump 5 extracts paint from the bottom of the paint storage chamber 2 through the paint extraction pipe 6 connected to its feed end, and transports the paint to the feed pipe 7. One end of the feed pipe 7 is connected to the paint pump 5, and the other end passes through the spray box 1 and extends into the spray room 25, and is finally connected to the paint spray pipe 20. The paint spray pipe 20 is fixed on the support 19 in the spray room 25, and is arranged in an inclined shape, and its discharge end corresponds to the centrifugal pump on the positioning plate 8. The paint is sprayed out through the paint spray pipe 20 to realize the spraying operation of the centrifugal pump. The design of the paint spray pipe 20 ensures that the paint can be evenly sprayed on the surface of the centrifugal pump.

[0034] During the spraying process, the centrifugal pump rotates and reciprocates through the combined action of the drive motor 15 and the electric push rod 16. The drive motor 15 makes the centrifugal pump rotate at a certain speed to ensure that the paint can evenly cover the entire surface of the centrifugal pump. At the same time, the electric push rod 16 moves the centrifugal pump up and down during the spraying process through the reciprocating motion of the push rod. This design ensures that the paint can be evenly sprayed to all parts of the centrifugal pump, avoiding uneven spraying caused by static spraying.

[0035] Two sealed doors 21 are hinged on the end surface of the spray box 1, corresponding to the spray room 25. The sealed door 21 is provided with an observation window, through which the operator can monitor the spraying process to ensure the spraying quality and the operating status of the equipment. The design of the sealed door 21 prevents the leakage of paint and odor during the spraying process, protects the health of the operator and the cleanliness of the working environment. In addition, an inspection door 22 is also provided at the position corresponding to the equipment slot 4 of the spray box 1, which is convenient for maintenance and inspection of equipment such as the paint pump 5, ensuring the long-term stable operation of the equipment.

[0036] In summary, the design of the automatic spraying device takes into account many aspects, including paint storage, stirring, preventing solidification, centrifugal pump fixing and adjustment, paint extraction and spraying, and dynamic adjustment of the spraying process. The design of the sealed door and observation window further ensures the safety of the equipment and the convenience of operation. The device can effectively solve the problems of uneven spraying of the centrifugal pump and paint solidification, and provide efficient and uniform spraying effects.
